Bill Nye specifically targeted the elderly this week as he spoke out against climate change deniers, saying that climate science will start to advance when old people start to "age out," according to a report.

The "Science Guy" said that generationally, the majority of climate change deniers are older.

"Climate change deniers, by way of example, are older. It's generational," Nye told the Los Angeles Times. Nye said that he is calling them out with "due respect," acknowledging that he is "now one of them."

"We're just going to have to wait for those people to 'age out,' as they say," Nye went on, adding that "age out" is a euphemism for "die." "But it'll happen, I guarantee you — that'll happen."

Nye's latest book, Everything All at Once: How to Unleash Your Inner Nerd, Tap into Radical Curiosity and Solve Any Problem, touches on climate change, personal success, and other societal issues.
